DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a wrapping apparatus according to an embodiment of the present invention will be described with reference to the drawings.
The wrapping apparatus according to the present invention is shown in, for example, FIGS. 1 (a) and 1 (b) respectively in predetermined areas of a wrapper film F that overlaps a box-shaped packaged product S such as cigarettes cut out at predetermined lengths. As described above, when the box-shaped package product S is overlapped with the wrapper film F, an embossing process is performed on a region positioned in a previously specified region. FIG. 1A shows an example in which a vertically long embossed region E1 is provided on the left side of the front side of the box-shaped package product S, and FIG. The example which provided the embossing area | region E2 which was located in the front center part and shaped the number [1] is shown.
[0009]
When the box-shaped package product S is overlapped by the wrapper film F having the embossed areas E1 and E2, the appearance images of the products are shown in FIGS. 2 (a), 2 (b), and 2 (c) for comparison. In addition, although the package designs (patterns) attached to the box-shaped package product S are the same, the appearance images thereof are different. In other words, by partially embossing, the transparency of the wrapper film F in that region is lost, and this makes the appearance of the package design (picture) attached to the box-shaped package product S different. As a result, the appearance image changes.
[0010]
FIG. 2 (a) shows an example in which the box-shaped package product S is overlapped with a colorless and transparent wrapper film F with a smooth surface that has not been embossed. FIG. 2B shows an example in which the packaged product S is overlapped with the wrapper film F provided with the above-described vertically elongated rectangular embossed region E1, and FIG. 2C shows the number [1]. The example which overlapped package goods S with the wrapper film F which provided the embossing area | region E2 is shown. Incidentally, in the example shown in FIG. 2B, the vertically rectangular design portion D1 of the package design (pattern) attached to the box-shaped packaged product S is covered with the vertically rectangular embossed region E1. The design portion D1 is visually expressed as a soft image. In the example shown in FIG. 2 (c), an embossed area E2 shaped with the number [1] is positioned in the blank area D2 of the package design (picture) attached to the box-shaped packaged product S. The appearance image is such that the number [1] is lightly attached to the blank area D2.
[0011]
Now, when the embossed areas E1 and E2 are formed on the wrapper film F and the wrapper film F is cut out at a predetermined length to overlap the box-shaped package product S, how is it attached to the box-shaped package product S? The problem is whether to emboss the area specified according to the package design. In other words, it is relatively easy to continuously emboss the long wrapper film F, but the package design attached to the box-shaped packaged product S of the wrapper film F cut out every predetermined length. In order to emboss only the area specified according to the above, a certain device is required.
[0012]
Therefore, in the wrapping apparatus according to the present invention, the package design (picture) attached to the specific region of the wrapper film F, that is, the box-shaped package product S that is overlapped by the wrapper film F, as shown below. Embossing is applied only to a specific area determined accordingly. That is, the wrapping apparatus according to this embodiment is basically configured as shown in FIG. 8 described above, and in particular, the wrapper film F is cut at a predetermined length in the feeding portion A of the wrapper film F. The embossing mechanism for embossing the wrapper film F is incorporated in synchronization with the cutting mechanism.
[0013]
Specifically, as shown in FIG. 3 which shows a schematic configuration of the feeding portion of the wrapper film F in the wrapping apparatus, the feeding portion A rotates in synchronization with the rotation of the suction belt roller 2 driven via the gear belt 1. A plurality of rollers for performing predetermined processing while feeding the film F are provided. The gear belt 1 is driven by being connected to a main shaft (not shown) of the wrapping apparatus, and thereby, a feeding portion A that cuts the wrapper film F into a predetermined length and sequentially supplies it to the conveyance path of the packaged product S. Is synchronized with the overlap processing of the box-shaped packaged product S by the wrapper film F in the wrapping mechanism B.
[0014]
The plurality of rollers that rotate in synchronization with the suction belt roller 2 are positioned on the downstream side of the suction belt roller 2 and are driven to rotate via an idle gear 3a. The suction belt roller 2 and a pair of embossed rollers 5a, 5b that are rotationally driven via an idle gear 3b, and a U-shaped knife roller 6 that is positioned further upstream and rotationally driven via an idle gear 3c ( Part of the cutting mechanism) and feed rollers 7a and 7b. Each of these rollers 2, 4, 5a, 5b, 6, 7a has the same roller diameter, and the outer peripheral length thereof is made equal to the cut-out length of the wrapper film F, thereby synchronizing each rotation every rotation A predetermined work is performed. In the figure, reference numeral 8 denotes a tension roller that applies a constant tension to the wrapper film F supplied to the feeding portion A.
[0015]
Incidentally, the feeding rollers 7a and 7b have a role of sandwiching the wrapper film F and feeding it to the feeding portion A, and the suction belt roller 2 has a role of sucking the wrapper film F and feeding the wrapper film F from the feeding portion A. I'm in charge. Therefore, the U-shaped knife roller 6 is formed in a U-shape that straddles the opening tape T on the portion of the wrapper film F that is transported in the feeding portion A as described above, where the opening tape T is adhered as described above. It plays the role of making partial cuts. The knife roller 4 plays a role of cutting the wrapper film F, which is U-shaped cut by the U-shaped knife roller 6, at the U-shaped cut portion.
[0016]
Thus, the pair of embossing rollers 5a and 5b positioned between the U-shaped knife roller 6 and the knife roller 4 are, for example, a predetermined pattern shape having male and female dies on each peripheral surface as shown in FIG. A pair of embosses 10a and 10b are formed, and the embosses 10a and 10b are arranged in parallel so that their axial directions are aligned with each other. The pair of gears 11a and 11b attached to the end portions of the embossing rollers 5a and 5b are meshed with each other so as to rotate reversely in synchronization with each other. As shown in FIG. Is sandwiched between the pair of embosses 10a, 10b so that the wrapper film F is embossed with the predetermined pattern.
[0017]
A backlash gear 11c is coaxially inserted into one of the gears 11a and 11b. The backlash gear 11c prevents the backlash between the gears 11a and 11b, and the pair of embossing rollers 5a and 5b rotate in synchronization with each other with high accuracy without causing a so-called rattling, and the pair of embossing 10a and 10b. Misalignment between them is prevented.
[0018]
In particular, the embossing rollers 5a and 5b configured as described above rotate in synchronization with the knife roller 4 and the like as described above, and rotate once every time the wrapper film F is fed out for a predetermined length. As a result, the U-shaped cutting position provided by the U-shaped knife roller 6, the embossing region embossed by the embossing rollers 5a and 5b, and the cutting position of the wrapper film F on the knife roller 4 are uniquely defined. The embossing is performed only on the specified region of the wrapper film F cut out at every predetermined length. Therefore, a pair of embosses 10a and 10b formed on the pair of emboss rollers 5a and 5b, respectively, in accordance with the package design attached to the box-shaped package product S which is overlapped by the wrapper film F cut every predetermined length. If the pattern shape and the formation position thereof are regulated in advance, it is possible to provide the wrapper film F with embossed areas E1 and E2 so that the box-shaped packaged product S can be positioned at a specific part when overlapping. It becomes.
[0019]
Thus, according to the wrapper film F which is cut out by a predetermined length through the feeding portion A configured as described above and fed out and used for the overlap of the box-shaped packaged product S, FIG. 6 (a) (b) As shown respectively, only a specific area in the predetermined length of the wrapper film F cut by including the U-shaped cut U is embossed to have embossed areas E1 and E2 having a predetermined shape. As a result, if the box-shaped package product S is overlapped with the wrapper film F subjected to such an embossing process, the embossing-specific optics is applied to the package design attached to the box-shaped package product S as described above. The product image can be made different.
[0020]
In addition, this invention is not limited to embodiment mentioned above. For example, if the wrapper film F can be transported uniformly by the suction belt roller 2 in the feeding portion A , the embossing rollers 5a and 5b may be provided on the downstream side of the knife roller 4 or the upstream side of the U-shaped knife roller 6. Is possible. The embossing roller 5a, the pattern of the embossing to be processed by 5b is naturally may be determined in accordance with the packaging design to be subjected to a box-shaped package product S. Further, the shape of the emboss itself is not particularly limited. In short, the present invention can be implemented with various modifications without departing from the scope of the invention.
[0021]
【The invention's effect】
As described above, according to the present invention, the wrapper film used for the overlap of the box-shaped package product is easily and accurately embossed only in a specific region synchronized with the cutting position. be able to. Moreover, by embossing the embossing mechanism in the roll-out part of the wrapper film, embossing can be performed effectively, and the image of package products that are overlapped by the wrapper film can be effectively enhanced.
